我有以下 ActiveAdmin 表单：

form do |f|
  f.inputs "Timesheet Details" do
    f.input :jobs_assigned_worker, :label => "Worker", as: :select, collection: Worker.all
    f.input :worked_time_hours,    :label => "Worked Time (Hours)"
    f.input :worked_time_mins,     :label => "Worked Time (Minutes)"
    f.input :driving_time_hours,   :label => "Driving Time (Hours)"
    f.input :driving_time_mins,    :label => "Driving Time (Minutes)"
    f.input :spent_dollars,        :label => "Extra Money Spent"
  end
  f.actions
end

当我在编辑视图中使用此表单时，选择下拉菜单会自动默认为当前值。但是在生产中，由于某种原因，下拉菜单默认为顶部的空白值（为什么那个空白值仍然存在？）。

编辑

问题似乎是 ActiveAdmin 不理解关联，默认无法选择关联对象。我需要弄清楚如何f.input为关联编码。该表格用于时间表。一个时间表has_manyJobsAssignedWorkers 并且每个 JobsAssignedWorker 都有一个 Worker。

如果要包含空白值：

f.input :jobs_assigned_worker,
  label: 'Worker',
  as: :select,
  collection: -> { Worker.pluck(:name) },
  include_blank: true

如果您不想包含空白值：

f.input :jobs_assigned_worker,
  label: 'Worker',
  as: :select,
  collection: -> { Worker.pluck(:name) },
  include_blank: false

如果您想要空白值，但又不想允许它作为选项：

f.input :jobs_assigned_worker,
  label: 'Worker',
  as: :select,
  collection: -> { Worker.pluck(:name) },
  include_blank: true,
  allow_blank: false

尝试设置“include_blank”选项。

form do |f|
    f.inputs "Timesheet Details" do
        f.input :jobs_assigned_worker, :label => "Worker", as: :select, collection: Worker.all, include_blank: false
        f.input :worked_time_hours,    :label => "Worked Time (Hours)"
        f.input :worked_time_mins,     :label => "Worked Time (Minutes)"
        f.input :driving_time_hours,   :label => "Driving Time (Hours)"
        f.input :driving_time_mins,    :label => "Driving Time (Minutes)"
        f.input :spent_dollars,        :label => "Extra Money Spent"
    end
    f.actions
end
